Abstract (en)
[origin: EP1757486A2] An optical axis controller (11) and method for headlamps for a vehicle where the swiveling lamps are not driven due to the minute steering operation of the driver. The steering angle of the steering wheel is detected by using, for example, a steering angle signal from a steering angle sensor (15). A desired light emission direction is computed based on the steering angle and a hysteresis value and the lamps (17a,17b) are driven to an actual light emission direction matching the desired light emission direction.
